So going off another post about crying it out. Sometimes when I have to do things around the house and I've already done everything I can like feeding, burping, diaper change, rocking, ect. And baby is still crying but I just need a break from holding them and theres nothing more I can do I lay my baby down and let them cry it out. Is that bad parenting? Or is it ok to do that when needed? If you can please provide actual scientific evidence that shows if this is safe or not. Whenever I here about self soothing so many moms say it's bad for babies health but id like to know why? I tried to find answers by looking it up. I'd like to know actual research done on the subject
